Patent JP-S6374323-A (JP)
Title: Current source circuit
Inventor: IMAMURA MAKOTO
IPC: H03M1/74
Filed: 1986-09-18
Abstract: PURPOSE:To expand the output impedance without using multi-stage cascade connection by providing a cascode FET J2 connected in series with a current source, a capacitor extracting a high frequency component from the source of the FET J2 and a means feeding back the harmonic component to the gate of the FET J2. CONSTITUTION:Only the harmonic component not responding to a current source 10 is extracted by a capacitor C1, it is amplified by a transistor (TR) 1 and fed back to the cascode FET J2. The capacitor C1 cuts off the DC current component fed to the base of the TR 1 and a capacitor C2 gives the same potential as a negative potential VE to the emitter of the TR 1 in terms of AC. Moreover, in terms of DC the collector potential of the TR 1 is set to a proper level by resistors R1-R3 and a bias voltage VB. Since only the high frequency component is fed back locally by the TR 1, the output impedance is increased without using a current source 10 having a good frequency response.

Title: Exposing and copying device
Inventor: YOSHIHARA HIDEO
IPC: G03B27/16
Filed: 1987-09-03
Abstract: PURPOSE:To speed up copying contact originals and to reduce the costs of an optical system by adjusting the diameter of a diaphragm for a projecting lens according as originals for forming and exposing images or those for contact exposure are loaded. CONSTITUTION:When a transparent original B of formed images is copied, light emitted from a light source 6 selectively transmits said original B, and its images are converged and formed on a photosensitive recording medium 13 through a projecting lens 8, and latent images of characters and pictures on said original B are formed on said medium 13. At that time, the projecting lens 8 is narrowed down to a prescribed value because image forming performance is prioritized. On the other hand, when a contact original A is copied, the diaphragm of the projecting lens 8 is opened, which is taken for a light condensing lens. After the contact original A is overlapped with the photosensitive recording medium 13, light is projected from the side of the original to perform exposure. Thus the quality of copied images can be maintained, and moreover the exposing time when closely adhering exposure is made can be shortened.

Title: Heat sink with fan
Inventor: TANABE SHOICHI
IPC: H01L23/40
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To keep a cold air flowing always in one direction by constituting a heat sink by including a fan fixed by screws to the side part of the heat sink. SOLUTION: The heat sink comprises a heat sink 2 having many columnar fins, spring 5 for mounting the heat sink 2 on the top face of a heating element 1 inserted in a socket 6 and fan 3 fixed by screws 4 to the side part of the heat sink 2 to blow air from the fan 3 to the heat sink 2. To avoid readily returning the warm air blown through the heat sink 2, a duct communicating with one face of a cabinet is disposed on the opposite face of the heat sink 2 to the fan, thereby improving the cooling efficiency. The fan 3 is reversely rotated to suck the warm air which is then exhausted out from the casing (via a casing fan) at the shortest distance. If the fan 3 is directly disposed on the casing, the effect more rises. A duct may be disposed between the fan 3 and casing.

Title: Economical manufacture of flow phosphorus-high manganese steel
Inventor: AOKI NOBUHIDE
IPC: C21C5/28
Filed: 1987-09-07
Abstract: PURPOSE:To manufacture a low P-high Mn steel at a low cost by reducing the amt. of P in molten pig iron to a specified value or below by dephosphorization, setting the amt. of C at the end of refining in a converter at a relatively high value and simultaneously carrying out decarburization and dehydrogenation by vacuum degassing. CONSTITUTION:When molten pig iron is dephosphorized, refined in a converter and vacuum-degassed to manufacture a steel, the amt. of P is reduced to <=0.040% in the dephosphorizing process and the amt. of C at the end of the refining process is set at >=0.06%, e.g., at the upper limit of about 0.10% so as to make the oxidation loss of Mn as small as possible and to increase the yield of Mn. In the vacuum degassing stage, decarburization and dehydrogenation are simultaneously carried out with an RH vacuum degassing apparatus, etc. Thus, a low P-high Mn steel can be advantageously manufactured.
